滇东黔西地区是华南区重要的煤层气资源分布区，晚二叠世成煤期煤层气盆地发育。本文概述了滇东黔西地区煤层气勘探目标评价。对该区进行了煤层气盆地的划分与评价；提出了煤层气系统的概念并对重点盆地的煤层气系统进行了研究；提出了煤层气区带的概念和煤层气地质风险分析的概念，对重点盆地进行了区带分析；对重点区带进行了煤层气藏预测及勘探目标优选；提出了煤层气重点勘探开发试验区。

EXPLORATION TARGET EVALUATION OF COALBED METHANE IN EAST YUNNAN-WEST GUIZHOU REGION

The East Yunnan—West Guizhou region is an important coalbed methane resource distribution area where the coalbed methane basins were developed in Late Permian.In the paper，the division and evaluation of coalbed methane basins are carried out for the East Yunnan—West Guizhou region according to its exploration target evaluation method of coalbed methane；the coalbed methane systems of some key basins are studied through putting forward the concept of coalbed methane system；the zones in some key basins are analyzed on the basis of proposing the concepts of coalbed methane zone and geological risk analysis；and some key testing areas of coalbed methane exploration and development are put formard in light of the results of the coalbed methane reservoir prediction and exploration target optimization of key zones.
